Subject: Reducing the verbosity of inserting a USB storage device
Date: Sun, 20 Sep 2009 16:53:49 -0600 [thread overview]
Message-ID: <20090920225348.GB3690@parisc-linux.org> (raw)
The current kernel is very verbose when you insert a new USB storage
device:
usb 1-2: new high speed USB device using ehci_hcd and address 9
usb 1-2: configuration #1 chosen from 1 choice
scsi4 : SCSI emulation for USB Mass Storage devices
usb-storage: device found at 9
usb-storage: waiting for device to settle before scanning
usb-storage: device scan complete
scsi 4:0:0:0: Direct-Access GENERIC USB DISK DEVICE 0100 PQ: 0 ANSI: 0 CCS
sd 4:0:0:0: Attached scsi generic sg2 type 0
sd 4:0:0:0: [sdc] 15728128 512-byte hardware sectors: (8.05 GB/7.49 GiB)
sd 4:0:0:0: [sdc] Write Protect is off
sd 4:0:0:0: [sdc] Mode Sense: 00 12 00 00
sd 4:0:0:0: [sdc] Assuming drive cache: write through
sd 4:0:0:0: [sdc] Assuming drive cache: write through
sdc:
sd 4:0:0:0: [sdc] Attached SCSI removable disk
I think we can print a bit less information, and format it more densely.
With the following three patches, my kernel prints:
usb 1-4: new high speed USB device using ehci_hcd and address 5
usb 1-4: configuration #1 chosen from 1 choice
scsi 6:0:0:0: Direct-Access Flash Disk 5.00 PQ: 0 ANSI: 2
sd 6:0:0:0: Attached scsi generic sg1 type 0
sd 6:0:0:0: [sdb] Assuming drive cache: write through
sd 6:0:0:0: [sdb] 2009088 512-byte logical blocks: (1.02 GB/981 MiB)
sd 6:0:0:0: [sdb] Removable disk, Write Protect is off
sdb: unknown partition table
which doesn't take up nearly as much of my syslog ;-)
